The Switch 2 Has Two Great New Features for Battery Health and Security
Help keep your Switch 2 healthy and secure.

Following its initial reveal early last month, Nintendo has been drip-feeding announcements about the Switch 2, and two announcements recently posted to the Nintendo Today app are especially exciting. The company revealed that your Switch 2 will have a feature that can limit charging speeds once it hits around 90%, in order to reduce battery degradation. But perhaps more exciting, especially for parents or kids with nosy siblings, is that you'll be able to use a PIN to lock your Nintendo Switch 2.
Set charging limits on Nintendo Switch 2

In a feature similar to the 80% charge limit on iPhones, Nintendo Switch 2 will optionally let you stop charging the device once the battery reaches around a 90% charge. This could help reduce battery degradation on your Switch 2, which could stave off repairs in the future. That said, the settings page mentions that your Switch 2 may still occasionally charge to 100% to ensure accurate display of the console's battery level.
Once you have your Switch 2, you can enable this feature by going to Settings > System > Stop Charging Around 90%. This is a great feature when you consider that many people will near permanently leave their Switch 2 in docked mode.
Lock your Switch 2 with a PIN

Got someone in your house that you don't trust with your console? The good old PIN lock is finally coming to the Nintendo Switch 2. The default screen lock on the original Nintendo Switch would require you to press a button thrice to unlock the console, which wasn't great for security. With the Switch 2, you can lock the console with a PIN, which is better for those who want to stop people from using their console without permission.
To enable a screen lock on your Switch 2, go to Settings > System > System Lock and enable the feature. This means that you'll have to enter a PIN every single time you wake the Switch 2 from sleep mode. Such is the price of improved security. Personally, the slight inconvenience is worth it for me, and I'm sure any parents with kids who are always trying to sneak in extra screen time would agree.
